Re: Permit Renewal Application—Sugar Creek WWTP
NPDES Permit#NC0024937; Charlotte Water
Mr. Montebello:
Please find the enclosed NPDES permit renewal application for Sugar Creek WWTP. The application
includes Attachments#1-8. The following is a summary of the attachments submitted with this
application:
1. Attachment#1 is a description of Sugar Creek WWTP's treatment process.
2. Attachment#2 includes a list of existing environmental permits as required in Section 1.6.
3. Attachment#3 includes the contact information and responsibilities for contractors working
at Sugar Creek WWTP as required in Section 1.25.
4. Attachment#4 addresses Section 2.2. and explains the ongoing work that CLTWater does to
minimize inflow and infiltration.
5. Attachment#5 includes the map required in Section 2.3.
6. Attachment#6 includes the plant flow schematic required in Section 2.4.
7. Attachment#7 includes a summary of scheduled improvements and the implementation
schedule as required in Sections 2.5, 2.6, and 2.7.
8. Attachment#8 includes a modified list of components to be included on the Supplement to
the Permit Cover Sheet.
The data summaries reported in this application include all effluent testing results at Sugar Creek WWTP
from October 1, 2020 through September 30, 2021. Parameters that are only collected during Effluent
Pollutant Scans, as required by Part 1 Section A. (7) of the permit, include data from all scans performed
since the current permit's effective date (October 1, 2017). Please note that some of the parameters for
which data has been submitted in this application have two method detection limits. This is due to a
change in the sensitivity of the analytical method or a change in the requirement to use a different
analytical method and/or report to a lower detection limit.
Please note that the wording of Section 1.16 ("Is effluent transported to another facility for treatment
prior to discharge?") has changed since the previous application form (A.8, d in previous application;
"Does the treatment works discharge or transport treated or untreated wastewater to another
treatment works?").Although Sugar Creek WWTP does still bypass some untreated wastewater to
McAlpine Creek WWMF (NC0024970), the response now reads "No" since effluent is not transported.

Additionally,the Supplement to the Cover Page of the current version of the permit does not reflect
recent changes made to the components at Sugar Creek WWTP.A modified components list has been
provided in Attachment#8.
Please let us know if you have any questions or if you need any further information. If you do, please
contact Shannon Sypolt, Water Quality Program Administrator, at 704/634-6984. You may also call me

Attachment #1 — Sugar Creek WWTP Narrative of Treatment Processes
Liquid Treatment Processes
Flow enters the Sugar Creek Wastewater Treatment Plant (WWTP)through Screening Facility#1 that
includes four%-inch mechanical bar screens.The Influent Pump Station then pumps to Screening Facility
#2 and Grit Removal that includes three 1/2-inch mechanical bar screens and two forced vortex grit
removal units.The Main Lift Pump Station lifts flow to four 110' diameter Primary Clarifiers. Primary
sludge is transferred to McAlpine Creek WWMF(NC0024945)via dedicated Sludge Transfer Piping.
Magnesium Hydroxide is added to the Primary Clarifier Effluent for pH and Alkalinity control before flow
is distributed between six equally sized Aeration Basins with a total volume of 4.1 MG. Each Aeration
Basin is equipped with an upfront Swing Zone with a Hyperboloid Mixer,Aerated Zones with Fine Bubble
Diffusers, and an Internal Mixed Liquor Recycle Pump that recycles flow from the end of the Aerated
Zone to the Swing Zone. Air is provided to the Aerated Zone via five High Speed Turbo Blowers.
After leaving the Aeration Basins, Mixed Liquor is split proportionally between four 85' and two 140'
diameter Final Clarifiers. Return Activated Sludge (RAS) is mixed with Primary Clarifier Effluent after the
addition of Magnesium Hydroxide, upstream of the Aeration Basins. Waste Activated Sludge (WAS) is
transferred to McAlpine Creek WWMF via dedicated Sludge Transfer Piping.
Final Clarifier Effluent is pumped to ten Monomedia Sand Filters. Backwash water from the Filters is
returned to the treatment process via the RAS line. Filter Effluent is Disinfected using UV Disinfection
before flowing to the Cascade Aeration Effluent structure to be discharged to Little Sugar Creek.
Solids Processes
The Primary Sludge and Waste Activated Sludge (WAS) from the Sugar Creek WWTP is pumped to the
McAlpine Creek WWMF and blended with the Primary Sludge and WAS from the McAlpine Creek
WWTP, prior to Anaerobic Digestion and Class B Land Application.
Auxiliary Processes
The Influent Pump Station also has the ability to pump flow to the 20 MG West Equalization Basin during
Wet Weather Events, and to be returned to the Plant Influent for treatment. Additionally, excess flow
from the Grit Removal units can be bypassed to McAlpine Creek WWMP for treatment, or to the 20 MG
East Equalization Basin during Wet Weather Events. Flow from the East Equalization Basin is drained to
the McAlpine Creek WWMF for treatment.
Alum can be added to Aeration Tank Effluent or Final Clarifier Effluent, as needed,for Phosphorus
Removal.
Sodium Hypochlorite is added to the Non-Potable Water(NPW) System,to control biological growth in
the NPW Piping.
Two Odor Control Systems are used,to control Odors from the Preliminary and Primary Treatment
Processes.
The Plant has three 2,200 kW Diesel Generators, for Full Facility Backup Power,with 20,000 Gallons of
Diesel Fuel Storage.

Attachment#4— Inflow and Infiltration (I&I) Reduction Practices
Charlotte Water (CLTWater) has maintained an established evaluation and rehabilitation program since
the early 1990's. The purpose of this program is to restore and preserve hydraulic capacity, structural
integrity, and to reduce corrective maintenance costs by addressing issues that cause SSOs. This includes
maintaining and implementing an on-going I/I reduction plan.
Multiple construction contracts are continually in place to address these issues. Through comprehensive
SSES efforts, including manhole inspections, smoke testing, CCN, flow monitoring, etc., areas are
identified for rehabilitation and work orders are assigned to a contractor. The work may include manhole
rehabilitation, point repairs, pipe lining, and pipe replacement.
From August 2010 to September 2021, CLTWater's Rehabilitation Team has:
• inspected 69,962 manholes
• smoke tested 9,163,110 ft. of pipe
• CCTV inspection of 1,680,963 ft. of pipe
These SSES efforts resulted in the following:
• 3,511 manholes rehabbed/repaired
• 661 inflow dishes installed
• 696,874 ft. of pipe rehabbed/replaced
• 1,406 clean-outs replaced
• 2,999 service laterals replaced
This does not include similar work performed by CLTWater's Field Operation Division or other sections
within CLTWater. CLTWater also implemented a chemical root control program in March 2005 and we
continue to maintain and expand that program. We have treated approximately 10,906,207 ft of line in
the McAlpine basin since this program was initiated.
CLTWater uses flow monitoring extensively to support engineering analyses, to prioritize sewer
improvements, and to evaluate capacity issues and I/I loadings in the major trunk lines in the system.
CLTWater currently has 60 permanent flow meters installed throughout the service area and utilizes
temporary flow metering on an as-needed basis.

Attachment #7 — Sugar Creek WWTP Scheduled Improvement
Section 2.5
Project Name UV Disinfection System Improvement Project
Scope of Work Project provides for replacement of existing UV disinfection system
that has been in service for over 15 years and is nearing the end of
its useful life. Project includes demolition of existing UV equipment
and replacement with new UV equipment and associated electrical
equipment,furnishing and installing a temporary disinfection
system during construction, modifications to existing UV equipment
channels, new UV level control finger weirs, new non-potable water
pumps, check valves, butterfly valves, and an air release valve, new
non potable pump control panels to include VFDs, new effluent
filter backwash return pump station wet well, submersible pumps,
and associated valves and piping and installation of a new
magnetic flow meter on the effluent filter backwash return piping.
